--------------------------------------
Summary: Enhance ByteStore exceptions with more context information
Key: KAFKA-6538
URL: https://issues.apache.org/jira/browse/KAFKA-6538
Project: Kafka
Issue Type: Improvement
Components: streams
Affects Versions: 1.2.0
Reporter: Matthias J. Sax
In KIP-182 we refactored all stores to by plain {{Bytes/byte[]}} stores and
only have concrete key/value types on outer layers/wrappers of the stores.
For this reason, the most inner {{RocksDBStore}} cannot provide useful error
messages anymore if a put/get/delete operation fails as it only handles plain
bytes.
Therefore, we should enhance exceptions thrown from {{RocksDBStore}} with
corresponding information for which key/value the operation failed in the
wrapping stores (KeyValueStore, WindowedStored, and SessionStore).
Cf https://github.com/apache/kafka/pull/4518 that cleans up {{RocksDBStore}}
exceptions.
